Critical minerals developers are increasingly using offtake agreements as financing instruments, with long-term supply contracts, prepayments, strategic investments and secured facilities becoming decisive factors in advancing mining projects.
Recent transactions across rare earths, battery minerals, tungsten, graphite, copper, cobalt and precious metals show a shift in how future supply is being developed. Buyers, commodity traders, governments and industrial groups are entering projects earlier, using commercial agreements to secure future production while helping companies move resources toward construction and operation.
Companies including Teck Resources, VHM, Arafura Rare Earths, Grande Portage Resources, Iluka Resources, Bezant Resources, Develop Global, Critical Metals, Nouveau Monde Graphite, EVelution Energy, Allied Critical Metals and USA Rare Earth have all been involved in recent offtake-linked financing structures. These agreements vary from production commitments and price floors to convertible notes, project loans, prepayment facilities and strategic equity investments, but they share a common objective: converting mineral resources into financeable projects.
Strategic Metals Agreements Link Government Funding With Future Supply
One of the largest examples involves Teck Resources, the Canada Growth Fund, and the Government of Canada through Teck’s Trail operations. The structure includes up to C$400 million from Canada Growth Fund and forms part of a wider investment pathway that could support up to C$850 million of Teck spending. The metals involved — germanium, antimony and gallium — are linked to defence applications, semiconductor manufacturing, solar supply chains and industrial technologies.
The arrangement demonstrates a growing role for governments as commercial participants in strategic mineral markets. Canada is securing offtake rights over part of future production, combining public investment with supply security objectives. Rare earth projects are also seeing increasing use of long-term commercial agreements.
Rare Earth Projects Secure Long-Term Industrial Buyers
Australia’s VHM Goschen rare earths and mineral sands project entered a strategic partnership with Iluka Resources, under which Iluka is expected to purchase 100% of Goschen’s rare earth concentrate production. The agreement is linked to an A$40 million convertible note package and covers reported production of 146,000 tonnes of concentrate containing approximately 86,000 tonnes of rare earth oxides over the contract period. For VHM, the agreement provides a defined downstream pathway for concentrate sales. For Iluka, it adds potential feedstock flexibility for its wider rare earth refining strategy.
Iluka has also secured its own binding offtake arrangement from the Eneabba rare earths refinery with an undisclosed global automotive manufacturer. The agreement covers magnet rare earth oxides including neodymium, praseodymium, dysprosium and terbium, with a reported value of approximately A$220 million.
The contract covers 1,200 tonnes over four years from 2028 under take-or-pay terms, representing around 10% of planned output during the period. The agreement reflects increasing direct involvement from automotive companies in securing refined rare earth supply rather than relying solely on indirect procurement channels.
New Rare Earth Agreements Expand Global Supply Networks
Arafura Rare Earths’ Nolans project has added another rare earth supply arrangement through an agreement involving an Indian industrial-group special purpose vehicle. The contract covers up to 500 tonnes per year of rare earth magnet feed for five years, with a possible two-year extension option. Pricing is linked to a seaborne traded index. The agreement provides a direct procurement link between future mine and processing capacity and India’s growing participation in rare earth supply chains.
Greenland’s Tanbreez rare earth project, controlled by Critical Metals, has also secured a long-term customer commitment. Critical Metals signed a definitive 15-year offtake agreement with REalloys, covering 15% of Phase 1 production. The financial value was not disclosed. The long contract period provides future demand visibility for the project and supports efforts to develop rare earth supply outside dominant Asian processing networks.
Gold and Base Metals Projects Use Offtake-Linked Funding
The same financing approach is appearing in precious and base metals. Grande Portage Resources secured a binding offtake agreement with Ocean Partners UK for the New Amalga gold project in Alaska. The agreement is connected to C$6 million in equity financing and a US$25 million construction loan and overrun facility.
For development-stage gold projects, these structures provide a pathway from resource definition toward construction financing while giving trading partners future access to production. Copper projects are also attracting similar arrangements. Bezant Resources signed a financing and offtake agreement for the Hope & Gorob copper project in Namibia with Hartree Metals. The package includes a US$7 million secured prepayment facility, while Hartree is expected to purchase 100% of copper concentrates for the life of the operation. The structure allows future concentrate production to support project funding while providing the trader with long-term marketing rights.
Commodity Traders Expand Role in Mine Development Finance
A larger-scale example comes from Develop Global’s agreement with Trafigura covering the Sulphur Springs/Yitirrti copper-zinc project and Pioneer Dome lithium direct shipping ore. The transaction combines binding offtake agreements with a financing package reported at US$400 million, including a US$350 million loan facility and US$50 million in warrants. The agreement highlights the role of major commodity traders in project finance. Traders can structure funding around future physical supply, marketing rights and commodity flows while projects continue through technical and development stages.
Graphite and Cobalt Projects Build Domestic Supply Chains
Battery minerals are also increasingly supported by long-term commercial structures. Nouveau Monde Graphite’s Matawinie mine in Québec secured a binding offtake agreement with the Government of Canada for 30,000 tonnes per year of graphite concentrate.
The agreement is structured as a long-term arrangement covering seven years. Graphite remains a challenging mineral to localise because China dominates both processing capacity and supply-chain expertise. The agreement supports Canada’s efforts to establish domestic battery-material supply chains while strengthening Nouveau Monde’s commercial foundation. Cobalt supply is following a similar pattern.
EVelution Energy signed a binding long-term cobalt offtake agreement with Mitsui valued at approximately US$850 million over five years. The agreement covers up to 3,000 tonnes per year of contained cobalt from EVelution’s planned Arizona facility. The structure creates a defined revenue framework for a U.S.-based cobalt supply chain as governments, battery manufacturers and automotive companies seek alternatives to concentrated refining networks.
Tungsten Financing Uses Price Protection Structure
Portugal’s Vila Verde tungsten project, developed by Allied Critical Metals, combines financing with a price protection mechanism. The company announced a US$40 million financing package for the pilot plant, including US$25 million of equity and US$15 million of project financing.
The offtake agreement covers 50% of production and includes a 2026 floor price of US$1,000 per mtu. Tungsten is used in defence, tooling, aerospace and industrial manufacturing applications. The price floor provides revenue protection against commodity price volatility and strengthens the project’s financing structure.
Rare Earth Acquisition Highlights Integrated Supply Strategy
The proposed acquisition of Serra Verde in Brazil by USA Rare Earth represents one of the largest strategic rare earth structures in the current market. Serra Verde has a 15-year offtake agreement covering 100% of Phase 1 production. The acquisition value was reported at approximately US$2.8 billion, alongside a cited financing package of around US$565 million.
The transaction reflects a broader move toward integrated rare earth platforms combining mineral resources, processing capacity, customer agreements and downstream magnet-market access.
Three Financing Models Emerge Across Mineral Markets
Recent transactions indicate three main structures developing across critical minerals markets. The first is the trader-backed model, represented by agreements involving Trafigura, Hartree Metals and Ocean Partners, where future concentrate or production flows support prepayments, loans and financing packages. The second is the industrial buyer model, seen in rare earth, graphite and cobalt agreements involving automotive companies, Indian industrial groups and strategic supply-chain participants.
The third is the government-supported strategic minerals model, demonstrated by Canada’s participation in Teck’s strategic metals development and Nouveau Monde’s graphite supply agreement. Across all three structures, offtake agreements are reducing uncertainty by linking future production with identified demand. A project supported by a credible buyer, defined pricing terms, production commitments or financing arrangements presents a stronger case to lenders than one relying only on future spot-market sales.
The latest agreements involving Portugal tungsten, Greenland rare earths, Canadian graphite, U.S. cobalt, Brazilian rare earths and Australian rare earths demonstrate a growing focus on contract-backed mineral development. Mining projects still require permits, infrastructure, technical execution and capital investment, but commercial agreements are increasingly becoming the foundation that connects mineral resources with financing decisions.
